CHARLES L. PERRY, OF EBENEZER, NEW YORK.

.CONCEALED CAR-DOOR LOCK.

To (all whom it may concern:

Be it known that 1, CHARLES L. PERRY, a citizen of the United States ofAmerica, residing at Ebenezer, county of Erie, and State of New York,have invented certain new and useful Improvements in Concealed Car-DoorLocks, of which'the following is a full, clear, and exact (.lescription.

The general object of my invention has been to provide a simple andeffective means, whereby a car or other door will. be come automaticallylocked when closed. Moreover, when my door is closed, it cannot beopened except by secret and concealed means, thus -preventingunauthorized persons from getting into a car provided with my lock.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which like characters of reference indicate likeparts throughout the several views of which Figure 1 is a side elevationof a equipped wit-hmy invention and portion thereof in section. Fig. 2is a secti nal view taken on line A ii of Fig. 1. Fig. 3 is a sectionalview taken on line CD of Fig. 1. Fig. +t is a fragmental sectional viewand shows a modified form of a portion of my invention as adapted forswinging doors.

in the drawings represents a sliding car door and 11 the track fromwhich it is slidably suspended.

12 is a fragmental DOIt-lUH of a box car or other inclosure and 133 isthe door-jalnb, which is suitably secured in place by any of the wellknown i'ncans.

From the rear side of the door antl near car door shows a t the front.edge thereof, is cut a recess 14:.

This recess extends from a point near the top edge of the door down tothe lowei' edge of the same. Communicating with the rc-- ccss 14 is arecess 15. The recess lSjis cut from the rear face of the door and openat the lower edge of the door and at the lower portion of the front edgeof the same.

Disposed within the recess 14 a lock bar it}. This lock haris arrangedto be in sliding contact with the front. side of the said recess and isprovided prefe 'ahiv near its central portion with suitable gait eways17. These guideways are preferably mad as shown, they being providedwith long arms 18 which extend back toward the rear Specification ofLetters Patent.

edge of the door, thereby providing means for securely and stronglyfastening the some to the door. Carried between the upper end of thesaid lock bar and the upper surface of the recess M is aspring 19 of anysuitfront end of this lever is provided With an.

upwardly turned projection 23. This projection is preferably in slidingcontact with the face 26 of the recess and is held in proper' placepreferably by means of the bolt This bolt isslidably disposed in a slot24 formed in the said projection, thus permitting the said operatinglever to be raised but preventing it from dropping down below the faceof the lower edge of the door. it plate 27 is set in flush with thefront edge of the door and is secured thereto, thus concealing theprojection of the said operating lever.

(arried by the door-jamb 13 is a lock bolt 28 which is provided at itsouter end with a conical point immediately behind which is provided anannular recess 30. This bolt projects beyond the face of the saiddoor-jainb so that when the door is pushed shut, the said recess will hein register with the lock bar 16. edge of the door is provided with asuitable aperture for the entrance of said lock bolt. The lock bar it;is also provided with an oblong aperture 36 which will register with thelargest diameter of the conical point 29 of the lock bolt 28 when thesaid lock bar is in its uppermost position. The width of the recess 30in the lock bolt is such as to permit the lock bar to be engagedtherewith when it in register with the same. The rear end of the lockbolt 28 is screw-threaded and is held in place preferably by means of asuitable nut 31 which is disposed Within a recess 32 let in from therear of the door-jainb 18, thus concealii-ig it from View. A pin 33 ispassed through the said lock bolt and the door-jau1b when the lock boltis ing or hinged doors, such'as provided on,

The front refrigerator cars and the like, some means must be providedfor withdrawlng the lock .boltwhen opening or closing the door. I

havepreferably carried out this part of my invention by the means shownin Fig. 4-, where 34 represents one of the swinging doors, which carriesa concealed casing 35. In this casing is slidably disposed a lock bolt43, which is provided with a conical point 37 and an annular recess 38.To the rear end of this look bolt is secured one end of a spring 39, theother end of said spring being suitably secured to therear end of thesaid casing. This keeps the said look bolt back within the casing 35 andflush with the face of the door 34:, when the door is not locked. In thecasing 35 and the front face of the door is provided a slot 40. A

. pin 11 is carried by the lock bolt 36 and is slidably disposed withinsaid slot, by means of which the said lock bolt may be pushed out andmadeto engage with the lock bar of the look. A plate tiZ-is secured tothe pin 41 and is in sliding contact with the view.

face of the door. This plate is wide enough to cover the slot 40 at alltimes, no matter what position the lock bolt may occupy, thuseiiectivelyconcealing the said slot from It. is of course understood that the otherdoor (not shown) is provided with the lock bar, operating l ver, etc.,as is shown in Fig. 1. For convenience in. the drawing, 1 have omittedto show this part of the device in Fig. 4:.

When my device is to be fitted to a single hinged door then the partotthe device shown in Fig. 1- is placed in the door casing.

.door to be opened. When the door is pushed shut the conical end of thelock bolt enters the aperture in the front edge of the door and strikesthe lock bar 16. The point of said lock bolt being conical it engagesthe upper side of the aperture 36 in the lock bar and raises the sameuntil the entire point 29 has passed therethrough, where upon. the saidbar, being under spring tension, will engage'with the recess 30 in saidbolt, thus securely locking the door;

W hen operating my invention on a hinged door, the operation is just thesame as above described, only instead of moving the door away from thelock bolt, this part of the device t) is drawn back into the casing 35.When looking the door, it is first closed and then the lock bolt 36 bymeans of the pin 41, is moved out and into engagement with the co-actingparts of the lock.

Obviously some detailed modifications may be made from the device hereinshown and described-without departing from the spirit of my inventionand I do not wish to be limited to the exact construction herein shownand described.

Having thus described my invention, what 1 claim is: v

1. The combination with a door provided with a recess near its frontedge and a door jamb; of a concealed locking devige com prising a lockbar slidably disposed in said recess and provided with an aperture, alock bolt carried said doo'r-jamb and provided with a conical point and.an annular recess behind said point, sald recess being engageable withsaid lock bar and concealed means for operating said lock bar.
